[c-nsp] QOS CBWFQ Problems

[Raymond Leung]

Dear Sirs :

I'm seeking for your expert supporting on my 6509 3CXL

Before , I've deployed an ACL for all IP running through VLAN800 with 36000000

However , I've checked my CACTI shown me it's just 4Mb traffic on the
limitation !

Right now , I've deployed the rule to transit for all including the violated

On the following information , you can check out my interface were
just running 50817000 , however the CBWFQ shown it's 75474008

Do you have any ideas on that ?

Thanks for your supporting !
